We see from your search that you're looking for information on the term "EMI filters",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Ceramic capacitors suit EMI filtering from
Syfer Technology, which we summarised at the time by saying "Syfer's discoidal multilayer ceramic capacitors can be installed directly into filters, onto bulkheads, hybrid circuits or onto printed circuit boards".
A couple of weeks before,
we featured the news release Compact outline for three-output switchers from
Nu Horizons Electronics Corp: "Triple-output universal-input 50W switching power supplies have a compact 50.8 x 101.6mm footprint and are less than 1U high".
In December 2007, we covered the news from California Micro Devices
concerning its CM1692 family
- take a look at Range cuts the cost of inductor-capacitor filters
which says: "LC filters allow mobile handset designers to address many higher bandwidth data interfaces that cannot be served by lower cost resistor-capacitor based devices".
Take a look also at the news release from Kyocera Corp, EMI filters use novel varistor material,
as well as Filter range covers standard and special needs from Focus EDL,
and EMI filters save space in power designs from TDK Electronics Europe.
